Comments Off on Einstein’s gravitational wave theory proven by the sound of two black holes colliding

Albert Einstein’s last unproven theory has finally been confirmed. Gravitational waves – ripples in space-time – have been confirmed to exist after decades of research and experimentation. The Laser Interferometer Gravitational-Wave Observatory (LIGO) proved Einstein’s theory with the observation of waveforms created by the collision of two black holes, an event long predicted but never before measured.

Comments Off on Tesla is getting ready to unveil its most affordable electric car to date

It’s the moment we have all been waiting for – Tesla is about to unveil the much anticipated Model 3 , its most affordable electric vehicle to date. The automaker is expected to release details of the $35,000 car on March 31, 2016, ahead of the vehicle’s market debut in 2017. The Model 3 will appeal to a much larger audience with its 200+ mile driving range and more attainable price tag.

Ultrathin grass condoms could make safe sex better than ever

Comments Off on Ultrathin grass condoms could make safe sex better than ever

Australian researchers at the University of Queensland have found a way to make latex condoms thinner, stronger, and more flexible than anything else on the market. The scientists extracted nanocellulose from a native variety of grass, spinifex, and used it as an additive in ordinary latex rubber. While a grass condom might sound a little strange, it turns out that adding the natural nanoparticles to rubber actually enhances the latex’s natural properties. This could be the first step toward overcoming some of the most common complaints about condoms reducing sensation during sex, and even enhance safety by making them less likely to break.

Computer Energy Efficiency Doubles Every 18 Months

Comments Off on Computer Energy Efficiency Doubles Every 18 Months

A new study done by an engineering professor at Stanford University has found that the energy efficiency of computers doubles roughly every 18 months, and has done so since the very first general purpose computer, the Electronic Numerical Integrator and Computer (ENIAC) that was built in 1956. With help from Intel and Microsoft, Professor Jonathan Koomey was able to gather information about computing devices from 1956 until now and with this new finding, Koomey is revising and improving Moore’s law — the observation that computer processing power doubles every 18 months.  Fortunately, the things that contribute to that power improvement (reducing component size, capacitance and communication time between them) also increase energy efficiency. This finding has great implications for the future of computers and battery-powered devices.  As we constantly increase the performance power of computers and gadgets, we’ll be improving their energy efficiency as well — a much needed trend as we become more reliant on our portable devices. Also, theoretically, we’re far from the limit of how much electricity we can save.  In 1985, physicists projected that we could improve computer energy efficiency by a factor of 100 billion and since then we’ve only hit a factor of about 40,000. via MIT Tech Review
